TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed. June 21, 1912. Serial No. 704,958.

To all whom it may concern:

Be it known that I, ARTHUR P. PAINn, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical chines, of which the following is a specification.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a dlstributing mechanism to the magazine from which they started.

In the Mergenthaler patent above men tioned, the distributing devices comprise rotating screws to convey the matrices along a grooved rail or bar, from which they are released at the proper points to return them to the appropriate channels in the magazine, and my invention is herein set forth in connection with that specific mechanism. Obviously, however, the principles thereof are capable of far broader application, and may be adapted to distinctly difierent styles of distributors, as well as to other forms of typographical machines, such for instance as those which handle type or dies instead of matrices. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, eX- cept in so far as such limitations are specified in the claims.

The principal specific object of the invention is to arrest positively the rotating distributer screws or equivalent devices, in the event that a type or matrix, while in rela tion thereto, is improperly checked or retarded, as for instance if it becomes lodged in the entrance to a magazine and there resists the normal operation of the screw or similar part. The screws or equivalent members are ordinarily synchronously rotated or operated, and I arrange them so that in the event of undue resistance, or

other similar derangement, this synchroanism has been nism will be interrupted, thereby calling into action certain connected parts, which ordinarily run freely but which in such circumstances are thrown out of their normal relations, and as a result thereof interfere and contact with each other so as positively to arrest the further operation of the screws or other members. Somewhat similar mechpresented in the application for Letters Patent of John R. Rogers, No. 687,691, filed Aprill, 1912, wherein are provided means in the form of eccentrics, specially formed gears, or the like, counted upon the screws in such manner that ordinarily they clear each other, but are thrown into interfering orbits when the synchronism of the rotating screws is disturbed, the result of this action involving their binding or contacting in such manner that the screws are positively arrested, and the breakage or bending of the parts, or of the type or matrices, being thereby avoided. In the said Rogers application, these eccentrics, gears, or the like, interfere and bind peripherally or by edge engagement with each other. In the employment of such devices, it sometimes happens that these peripheries or teeth do not engage instantaneously, or even if so engaged, that a certain amount of slip or relative motion occurs, thus permitting a slight rotation of the screws before their final arrest.

It is the purpose of the present invention to decrease still further this final rotation and to provide means whereby the operation is more speedily checked. To this end I employ interfering or contacting means,

which act upon each other by lateral engagement, as distinguished from the edge or peripheral engagement disclosed in the said Rogers application, my improved devices being arranged so that their effective binding or contacting occurs almost immediately and so as to reduce the further rotation of the screws to a minimum.

Referring to the drawing: Figure 1 is an end view of the distributing mechanism, partly broken away, and having my invention applied thereto; Fig. 2 is a section, taken substantially on the line 2-2 in Fig. 1; and Fig. 3 is a perspective view, showing the interfering members detached.

The matrices X are released from the distributor rail or bar R and pass into the magazine entrance M in the usual manner,

' that set forth in the said Rogers applicaapplication,

tion. For present purposes, it is necessary merely to consider the relative operation of the two screws A and B on the latter of which is loosely mounted the pinion G. In the illustrated instance, the positive stop members are in the form of two disks A and B, mounted rigidly upon the ends of the screws A and B As in the said Rogers the loose gear C on the screw B is connected to the disk B by the spiral spring D, whereby the gear is held in normal relation to the other parts, the turning action of the spring being ordinarily limited by the contact of the pins B and O upon the disk B and gear C, respectively.

The disks A and B are arranged so that ordinarily they run freely in relation to each other, but will engage laterally in the event of an interruption to the synchronism of the screws, due to undue resistance, or the like. I preferably form them with inclined or spirally arranged flanges, in effect like transverse sections of screws, the threads of which mutually penetrate each other. For instance, as shown in the drawing, the flange o of the disk B is located between the two flanges (4 (4 of the disk A, at the particular point of operation illustrated in Figs. 2 and 3. In this position the flange a of the disk A, and the flanges 6 b of the disk B, are shown at opposite points and as disengaged, but when the screws have rotated through an angle of 180, the flange a will then be contained between the flanges 6 b and the flanges a a and b, will be separated. In other words, in ordinary operation the disks A and B run freely in relation to each other, but with their respective flanges or threads always in lateral proximity. If for any reason, such as undue resistance or the like, the synchronism of the screws be interrupted, the disks will be angularly shifted with relation to each other, resulting in the lateral contact of their respective spiral threads, and the immediate and positive arrest of the screws.

As previously stated, I have shown my invention in preferred form and by way of example, but its principal object is the immediate stoppage of the screws, and this I specifically effect by the engagement of the spiral threads. However, the generic feature involved is the employment of laterally acting pressure to effect the result, and this may be secured in many ways.

Obviously many variations and alterations in the means, as well as in their mode of application, will suggest themselves to those skilled in the art and still be comprised within the scope of the invention.

Having thus described my invention, its construction and mode of operation, what 1 claim and desire to secure by Letters Patent of the United States is as follows:

1. In a typographical machine, the com bination of a distributing device, with arresting means therefor comprising cooperating rotary members which engage laterally and lock in rendering said means operative.

2. In a typographical machine, the combination of a rotary distributing device, with arresting means therefor comprising cooperating rotary members mounted to clear each other normally but to engage laterally and bind when their normal rotation is interfered with.

8. In a typographical machine, the combination of two synchronously-operated rotary distributing devices, with arresting means therefor comprising two cooperating members connected to the respective distributing devices and formed to engage laterally when the synchronous operation of said devices is disturbed.

l. In a typographical machine, the combination with two rotatable distributing devices normally operating in unison and one capable of a slight independent rotation relatively to the other, of arresting means therefor comprising cooperating members carried by the respective devices and formed to engage laterally when such independent rotation takes place.

5. In a typographical machine, the combination of a rotary distributing a device, with arresting means therefor comprising cooperating members provided with spirally-formed surfaces to engage and bind in rendering said means operative.

6. In a typographical machine, the combination of a rotary distributing device, with arresting means therefor comprising rotary disks formed to engage both laterally and peripherally in rendering said means operative.

7 In a typographical machine, the combination of a rotary distributing device, with arresting means therefor comprising cooperating spirally-threaded members, the threads on the respective members being so related as to permit their normal rotation but to contact and bind when their normal rotation is interrupted.

8. In a typographical machine, two rotary distributing devices, one rotatable independently relatively to the other, and provided respectively with cooperating spirally-surfaced members which are thrown into engagement by the independent rotation of said distributing device.

9. In a typographical machine, the combination of two rotary distributing devices,
